So?..Does this mean that all former Catholics are condemned to hell because they left the church because they have concluded that it is corrupt and in error? Do you see how such a teaching above is cult-like in its emotional manipulation?
No. If they are sincerely following the promptings of their conscience, of course they are not damned.
I.e., some who leave the Catholic Church may be saved, others who leave the Catholic Church may be damned. Everything depends on their intellectual honesty.
